TECHNICAL FIELD

The present invention relates generally to methods and apparatus for locating wireless devices, also called mobile stations (MS), such as those used in analog or digital cellular systems, personal communications systems (PCS), enhanced specialized mobile radios (ESMRs), and other types of wireless communications systems. More particularly, but not exclusively, the present invention relates to using location and identity information collected by wireless location systems (WLSs) and wireless communications networks (WCNs) to calculate relationships between mobile subscribers and then managing location generation resources based on location priorities, required quality of service and resource availability.

BACKGROUND

Location has always been a feature of mobile communications systems. With the advent of cellular radio systems, inherent in the functions of the wireless communications networks (WCNs) were the concepts of cell, sector, paging area and service area. These radio coverage areas created within the WCN had a one-to-one correspondence to geographic areas, but were of limited use in enabling location-based services outside of the provision of communications between the mobile device and the WCN.

As part of the Personal Communications System (PCS) auction of 1994, the Federal Communications Commission, at the behest of public safety agencies, added a requirement for the location of wireless emergency services calls for cellular and PCS systems. The FCC's wireless Enhanced 9-1-1 (E9-1-1) rules were designed to improve the effectiveness and reliability of wireless 9-1-1 services by providing 9-1-1 dispatchers and public safety agencies with geographic location information on wireless 9-1-1 calls. Location accuracy varied from the E9-1-1 Phase I rules which required that the existing WCN developed location information be converted to a geographic representation and made available to public safety agencies. Phase II of the FCC E9-1-1 rules called for high-accuracy location of emergency services wireless calls. Eventually both network-based and mobile-based techniques were fielded to satisfy the E9-1-1 Phase II high accuracy location mandate.

As realized and noted in extensive prior art, the ability to routinely, reliably, and rapidly locate cellular wireless communications devices has the potential to provide significant public benefit in public safety and convenience and in commercial productivity. In response to the commercial and governmental demand a number of infrastructure-based, handset-based and network-based wireless location systems have been developed.

Infrastructure-based location techniques use information in use within the WCN to generate an approximate geographic location. Infrastructure-based location techniques include CID (serving Cell-ID), CID-RTF (serving cell-ID plus radio time-of-flight time-based ranging), CIDTA (serving cell-ID plus time-based ranging), and Enhanced Cell-ID (ECID, a serving cell, time-based ranging and power difference of arrival hybrid). Signals that generate the WCN information that is the precursor to infrastructure-based location may be collected at the handset or at the base station and delivered to a mobile location server which has databased knowledge of both the WCN topology and geographic topology.

Network-based location solutions use specialized receivers and/or passive monitors within, or overlaid on, the wireless communications network to collect uplink (mobile device-to-base station) signals, which are used to determine location and velocity of the mobile device. Overlay Network-based techniques include uplink Time-Difference-of-Arrival (TDOA), Angle-Of-Arrival (AOA), Multipath Analysis (RF fingerprinting), and signal strength measurement (SSM). Examples of network-based systems for the determination of locations for wireless mobile units are found in Stilp, et al., U.S. Pat. No. 5,327,144; Stilp, et al., U.S. Pat. No. 5,608,410; Kennedy, et al., U.S. Pat. No. 5,317,323; Maloney, et al., U.S. Pat. No. 4,728,959; and related art.

Mobile-device based location solutions use specialized electronics and/or software within the mobile device to collect signaling. Location determination can take place in the device or information can be transmitted to a landside server which determines the location. Device-based location techniques include CID (serving Cell-ID), CID-RTF (serving cell-ID plus radio time-of-flight time-based ranging), CIDTA (serving cell-ID plus time-based ranging), Enhanced Cell-ID (ECID, a serving cell, time-based ranging and power difference of arrival hybrid), Advanced-Forward-Link-Trilateration (AFLT), Enhanced Observed Time Difference (E-OTD), Observed-Time-Difference-of-Arrival (OTDOA) and Global Navigation Satellite System (GNSS) positioning. An example of a GNSS system is the United States NavStar Global Positioning System (GPS).

Hybrids of the network-based and mobile device-based techniques can be used to generate improved quality of services including improved speed, accuracy, yield, and uniformity of location. A wireless location system determines geographic position and, in some cases, the speed and direction of travel of wireless devices. Wireless location systems use uplink (device-to-network) signals, downlink (network-to-device) signals, or non-communications network signals (fixed beacons, terrestrial broadcasts, and/or satellite broadcasts). Network-based location solutions use specialized receivers and/or passive monitors within, or overlaid on, the wireless communications network to collect signaling used to determine location. Network-based techniques include uplink Time-Difference-of-Arrival (TDOA), Angle-Of-Arrival (AOA), Multipath Analysis (RF fingerprinting), and signal strength measurement (SSM). Hybrids of the network-based techniques can be used to generate improved quality of services including speed, accuracy, yield, and uniformity of location.

The use of collateral information supplied to the Wireless Location System from the Wireless Communications Network or off-line databased to enable or enhance location determination in network-based systems was introduced in Maloney, et al., U.S. Pat. No. 5,959,580; and further extended in Maloney, et al., U.S. Pat. Nos. 6,108,555 and 6,119,013. These and related following descriptions of the prior art for infrastructure-based location determination systems enable robust and effective location-determination performance when adequate measurement data can be derived or are otherwise available.

Since the advent of direct dial cellular telecommunications in 1984, and especially in the past decade, the cellular industry has increased the number of air interface protocols available for use by wireless telephones, increased the number of frequency bands in which wireless or mobile telephones may operate, and expanded the number of terms that refer or relate to mobile telephones to include “personal communications services,” “wireless,” and others. Also, data services, such as short-message-service (SMS), packet data services (for example the GPRS (GSM General Packet Radio Service) and IP Multimedia Subsystem (IMS) have proliferated as has the number and variety of voice, data and voice-data capable wireless devices.

The air interface protocols now used in the wireless industry include AMPS, N-AMPS, TDMA, CDMA, TS-CDMA, OFDM, OFDMA, GSM, TACS, ESMR, GPRS, EDGE, UMTS, WCDMA, WiMAX, LTE, LTE-A and others.

The term CDMA will be used to refer to the CDMA digital cellular (TIA/EIA TR-45.4 defined IS-95, IS-95A, IS-95B), Personal Communications Services (J-STD-008), and 3GPP2 defined CDMA-2000 and UMB standards and air interfaces. The term UMTS will be used to refer to the 3GPP specified Wideband-CDMA (W-CDMA) based Universal Mobile Telecommunications System, defining standards, and radio air interface. The term WiMAX is used to denote the IEEE defined 802.16, “Broadband Wireless”; 802.20, “Mobile Broadband Wireless Access”; and 802.22, “Wireless Regional Area Networks” technologies. The present invention also applies to the 3GPP defined Long-Term-Evolution (LTE) and the 3GPP LTE-Advanced (LTE-A) system among others.

SUMMARY

A Location Intelligence Management System (LIMS) is a data capture, storage and decision support system that utilizes available data (both past and real time) from multiple sources (such as wireless networks, wireless location network, and off line sources such as network information, geographic information, manually entered information and geo-spatial data) to optimize utilization (scheduling and selection) of wireless location resources across multiple users and entities to produce location-aware intelligence. The LIMS contains the algorithms, control logic, data storage, processors and input/output devices to analyze past and real time data obtained from multiple sources in combination or separately, to produce intelligence in the form of metadata not otherwise reasonably or easily obtained. These algorithms can iteratively use previous generated metadata to automatically contribute to new analysis, which will use both real data (past and real time) as well as metadata. Such analysis would produce information such as: identifying potential behaviors of interest, identifying specific mobile users associated with such behaviors of interest, associations between mobile device users and mobile device user identification when no public ID is available (such as with prepaid mobile devices). The LIMS can then manage Position Determining Equipment (PDE) location resource utilization based on a combination of factors including but not limited to location priority, location accuracy, wireless location system(s) capacity, the geographic distribution of PDEs, terrain, man-made information (known tunnels, buildings, bridges, etc.), network information (cell distribution, coverage, network topology, network status, etc.), for performing locations on traffic channels, control channels and data sessions.

In an illustrative embodiment, a LIMS comprises a controller computer, a first database configured to store network event historical data, and a second database configured to store metadata. The LIMS is configured with computer software to utilize data from multiple sources to produce location-aware intelligence. This includes the creation of geo-profiles for mobile devices. The geo-profiles include location and time information for the mobile devices.

Such geo-profiles can be analyzed to detect aberrant or potentially aberrant behaviors, or what we refer to as “behaviors of interest,” or “behavior-based triggers”. For example, as described below, an aspect of this embodiment is the LIMS' capability to detect behaviors of interest and identify specific mobiles or mobile users associated with such behaviors of interest. These behavioral complex triggers use the LIMS capabilities that allow radio or network events corresponding to specific messages or groups of messages to generate high and/or low accuracy location estimates. A triggering event that initiates location estimation may be a detection of a particular message or a field within a specific message. Over time, a database of historical information including mobile identifiers and triggered events is developed (collection phase). The data collection phase may target any mobile device, any set of mobile devices, or a specific area in the wireless communications network (WCN) service area. Selection of a mobile device may be by any of the detectable mobile or network identifiers associated with the mobile device. Data from the collection phase is then analyzed for suspect behaviors and an index probability is assigned to each mobile. The analysis phase may include information imported from off-line sources and may be performed periodically, ad hoc in response to a set triggering event, or manually at any time. Illustrative examples of advanced LIMS scenarios include area presence determination, association by proximity, detection of avoidance tactics, and general surveillance using secondary triggers. Additional aspects in the inventive subject matter are described below.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

We will now describe illustrative embodiments of the present invention. First, we provide a detailed overview of the problem and then a more detailed description of our solutions.

FIG. 1A illustrates the LIMS as deployed in a generic wireless communications Network (WCN). The Radio Access Network (RAN) 101 provides the radio link between the mobile device and the Core Network 102. Examples of a RAN network can include the Global System for Mobility (GSM), iDEN, Tetra, Universal Mobile Telephone System (UMTS), WiMAN, WiMAX, Long-Term-Evolution (LTE), Generic Access Network (GAN), and the IS-95/IS-2000 family of CDMA protocols among others. The Core Network provides the basic switching, routing, transcoding, metering, and interworking needed to connect and bill mobile-to-land, land-to-mobile, and mobile-to-mobile connections. The core network connects to landside networks and other mobile networks via the Public Interconnection Network 103 (nominally a SS7 network with trunking for circuit switched connections or a TCP/IP network for digital packet data connections.

The LIMS 108 subsystem is connected to the RAN 101 and Core Network 102 via the Link Monitoring System (LMS) 106. As disclosed in TruePosition U.S. Pat. No. 6,782,264, Aug. 24, 2004, “Monitoring of Call Information in a Wireless Location System,” and U.S. Pat. No. 7,167,713 “Monitoring of Call Information in a Wireless Location System” and then expanded in U.S. Published Patent Application 20060003775, filed Jun. 10, 2005, “Advanced Triggers for Location-based Service Applications in a Wireless Location System,” an Abis Monitoring System (AMS) or Link Monitoring System (LMS) 106 can be deployed in conjunction with the wireless location system to supply a passive means of triggering and tasking the wireless location system. As cost savings measures, an LMS 106 may be deployed to monitor the Abis (BTS-to-BSC) link only or the required LMS functionality may be incorporated directly into the BSC. Full functionality of the LMS in identifying wireless transactions, network transactions, mobile identifiers, and subscriber identifiers requires that the example GSM network, the A, Abis, and GSM-MAP interfaces, be monitored. The LMS 106 functionality can be deployed as a network of passive probes reporting back to a central server cluster or as a software-based application for inclusion in wireless infrastructure, for example, the Base Station Controller (BSC) or Radio Network Controller (RNC). The LMS 106 connects to the RAN 101 via a digital data connection 104 and to the Core Network 102 via a digital data connection 105. The LMS 106 connects with the LIMS 108 via a digital data connection 111. The LMS 106 may optionally connect with the Position Determining Entity 114 via a digital data connection 115 in cases where triggers and filters, and priorities pre-set in the LMS 106 by the LIMS 108 require a minimum latency in initiation of the location signal collection and calculation.

The LIMS 108 is a set of generic computer servers and routers running specialized interconnected software applications and databases. The LIMS 108 connects via digital data links 112 113 to multiple databases which at minimum include a network event historical database 110 and a metadata database 109. The LIMS 108 is a decision support system that determines when and how accurate a specific wireless location needs to be and where to best obtain it from given current conditions (for example, how busy different PDEs are or the concentration of concurrent requests for locations in a given geographic area). The LIMS then manages PDE 114 location resource utilization based on a combination of factors including but not limited to: priority, accuracy, system(s) capacity, geographic distribution of PDEs, terrain, man-made information (such as, known tunnels, buildings, bridges), network information (cell distribution, coverage, network topology, network status), for performing locations on traffic channels, control channels and data session locations. Information on man-made features may include elevation and altitude data. Man-made features include transportation structures (bridges, overpasses, tunnels) as well as industrial and habitable structure information.

The LIMS 108 manages location resources based on prioritization level, resource availability, and demanded location quality of service. The LIMS 108 contains a decision support system (DSS) software application to automatically decide when to require a high accuracy location versus a lower accuracy location which does not require potentially limited PDE 114 location resources. The DSS application uses rules, databased location, identity, and transactional information (network or mobile events, time of day, geo-fence boundaries) to determine a set of scenarios based on a prioritized set of situational issues that generate metadata (which is stored in a metadata database) such as relationships between users, mobile devices, locations of interest and other mobile devices. Using the multidimensional histograms of activity and locations with dynamic conditional logic, the LIMS can determine association by proximity which can then be used as a triggering event or use location as a proxy to identity (metadata) users and relationships between users, groups and locations of interest. In setting the automatic real-time, high-accuracy location of mobile devices, the metadata analysis is used by the DDS application to compile an iterative, “Risk profile”, escalating number on accumulation of weighted patterns and factors for each device, Mobiles with a high risk threshold, as determined by behaviors e.g. such as entry or exit to secured areas, communication with or proximity to known suspects, or communication patterns indicative of known avoidance patterns, are subjected to additional scrutiny and potentially flagged to users.

The LIMS 108 receives infrastructure-generated tasking information en mass from the LMS 106 to obtain data for real time processing of currently running algorithms, to populate the network event historical database 110 for future analysis as well as details required to enable the network based location system (PDE) to perform higher accuracy locations as required. The network event historical database 110 contains all events from all “simple” triggers set in the LMS, these events include mobile identifiers (such as IMSI, IEMI, MS-ISDN, TMSI) event details (such as called number, calling number, message type) as well as location information gleaned from the wireless network parameters obtained from the event reports. The LIMS 108 creates its own complex triggers from the combination of the real time flow of mass data into the operating algorithms, use of past network event historical data 110 and past metadata database 109 and use of the DSS that optimized PDE utilization previously mentioned.

Examples of the LIMS 108 capabilities enabled by the network event historical database 110 include geo-profile (locations and events as a function of time, probability and pattern analysis) determination, associations by proximity (correlation between two or more devices based on location proximity as a function of time and based on probability and pattern analysis in consideration of accuracy and other factors) based on histograms and conditional logic, detection of past patterns of evasive behavior (such as SIM swapping, use of multiple SIMs by the same user, use of multiple phones carried by the same user, turning mobile devices on only briefly, turning mobile devices off and on at specific locations frequently). The LIMS 108 can use a mobile's calling pattern and history for analysis, but more importantly, it can use non call related information such as registrations and location updates for additional analysis to build improved geo-profiles and associations by proximity to then recognize suspicious behavior and events. The network event historical database 110 includes records on both messaging-related and WCN control events like location updates, handovers, power up IMSI attaches and power down de-registrations). Additionally, information from the metadata database 109 (containing non-wireless, non-transmitted or generated information) can be also be used in the decision matrix. For example, user entered information on geographic areas of interest, known special terrain conditions or specific case information can be used to add additional intelligence for filtering and correlative analysis. Additionally, the metadata database 109 contains data generated from past execution of algorithms (such as geo-fence operations, targeted surveillance activity) is maintained and can be used.

A geo-profile is created for each mobile device and will include the location of the mobile as a function of time for a specific time range or area of interest. Such geo-profile is metadata that is created from network transactions (single to multiple) monitored by the LIMS platform as well as from off-line sources and LIMS created meta-data derived from post-processing analysis and multi-transaction complex triggers. When a geo-profile of a mobile is focused on a specific area of interest, this is called a geo-fence profile.

For instance, a geo-fence profile can include where a mobile spent time in or out of a specific geographical area is recorded as a function of time, or as a time value as a function of area.

For each network transaction monitored, a network transaction record (NTR) is created and appended to the geo-profile. Analysis of the contents of the NTR may be in real-time or performed in a post-processing stage. The timing and priority of analysis may be based on any field in the NTR. Results of the analysis are then added to the geo-profile.

An example of the NTR is shown in Table 1 and illustrative details of the record are shown in Table 2. Exact details of the NTR contents are dependent on the probe system deployed. For instance, a wireless communications network based software-based probe (located in the GSM Base Station Controller, the UMTS Radio Network Controller, or the LTE Serving Gateway Mobility Management Entity) may deliver different information then a passive overlay/independent probe network.

TABLE-US-00002 TABLE 2 Network Transaction Record Detail TS—this is the timestamp data for the triggering event ID—this is the collected identification information for the mobile device (e.g. MSISDN, IMSI, IMEI, TMSI) KEY—Any information for the network transaction that includes Encryption Key data (either collected by or delivered to the LIMS) TRIG—The index to the triggering event EV—The Event(s) descriptor and details. This is in addition to the triggering information and can include called number, calling number, location area CELL—this field includes data about the wireless communications network. Example data includes serving Cell ID, Serving Cell Location, Serving Network Name, Network ID, Country Code, Country, Wireless Operator technology, and available Location Technology. EXT—Extended information on WCN radio link such as timing parameters (e.g. Timing advance, Round Trip Time or Serving-One-Way-Delay) and link power (e.g. Measurement Reports, Network Measurement Reports, Code Power Measurements, or Pilot Strength Measurements). Both uplink and downlink information on the radio link LOC—When a location is triggered, the Mobile Device location, velocity and uncertainties for location and velocity are stored. GEO—Includes geo-fence information if mobile is interacting with a set geo-fence area or boundary. This field includes geo-fence Name, geo-fence breach, breach direction, Breach Type, Breach Frequency, Breach time. RISK—A risk parameter is set for each mobile device and is set on the basis of each event, and each geo-fence. This field is incremented and decremented in accordance to the rules and priorities set by the LIMS operator.

In the U.S. Pat. No. 7,783,299, issued Aug. 24, 2010, entitled “Advanced Triggers for Location-Based Service Applications in a Wireless Location System”, TruePosition introduced the basic concept of triggers allowing for the monitoring of WCN for events and transactions that would automatically cause a location attempt based on the pre-set triggers. Use of the LIMS 108 with its decision support system (DSS) and historical and metadata database(s) enable a new class of triggers based on an additional layer of logic and filtering based on historical or off-line data. The basic trigger delivered information and other data is processed by the DSS with a set of if-then-else rules combined with databased information on events, time-of-day, and geo-fence boundaries to create a database of metadata. The newly created metadata allows the LIMS to perform analysis where the location of a mobile is used as a proxy to identity, purpose and relationships with other mobile users. The same metadata can be used to enhance forward looking algorithms which in turn produce new complex triggers.

An example of a complex trigger than uses network event historical database 110 in conjunction with real time network information is a when two or more mobile devices exhibit the same location behavior over a period of time, such as being co-located while moving around for periods of time, implying they are traveling together, but there is no information in the historical database indicating they ever interact with each other (e.g. voice call, connection via data session or Short-Message-Service (SMS)). Then, the LIMS can decide to utilize high accuracy PDE resources to further verify or dispute this heuristic information. Such high accuracy locations would be based on real time network events, either passive or actively generated to determine location of said subjects at the same point in time. This can remain in operation for extended periods of time to increase confidence in the correlation.

Another example is the automatic detection of SIM swapping based on historical data as compared to the real time data coming in from the network. Once detected, the LIMS can then decide to trigger the PDE to locate the mobile(s) using high accuracy at that point in time or on a continuous basis depending on the user conditions set up in the LIMS such as location area where this occurs, time and day constraints, proximity to other known mobile devices, etc. Automatic use of high accuracy location helps build up a set of high accuracy information in the metadata database for a set of high risk mobile devices and their users for future correlation with other mobile devices, public events (such as crimes, public gatherings, etc.) sites and points of interest (such as tunnel entry/exit point, overlook observation points) as the high accuracy resources are limited and cannot be provided for every mobile and every network event.

Network Event historical database 110 (may actually be one or more databases) contains information on every network event transaction that occurs in the covered area for all mobile devices as configured. This could be reduced to a specific set of mobile devices via a list of identifiers for inclusion only or exclusion only. Said database contains selected information for each event including all available known identifiers of the specific mobile (one or more of the following: TMSI, IMSI, IMEI, MSISDN). It also includes event related information including the event type (such as hand over, mobile originated call, SMS received, etc.) and related event data such as dialed digits and timestamps. Additionally, each event contains relevant network information depending on the network type (cell site and TA for GSM, CI and SAI for UMTS, etc.). The network event historical database also includes some metadata for each specific event (not related to other events or combinations) which includes a calculated X, Y location based on best available location processing (including high accuracy) as well as additional identifiers populated (such as MSISDN) that may not have actually existed in the network event but are known to belong to the said mobile device through correlation previously provided in the LMS or LIMS.

Metadata database 109 (may actually be one or more databases) contains information that is input by users (manually or automatically) and information that is produced as a result of processes or algorithms on the LIMS 108. User input data can contain maps information including but not limited to streets, terrain, clutter, buildings, foliage, tunnels, pipelines, facilities (airports, bases), sites or areas of interest (such as buildings or border crossings points or geo-fence definitions), can also contain network information including but not limited to cell site locations, antenna sizes, azimuths, directions, down tilt, can include high accuracy location results for specific algorithms that have run in the past (such as geo-fence operations or surveillance operations) as well as specific information related to conditions and parameters used in past algorithm runs.

LIMS Platform in GERAN Network

FIG. 1B details functional nodes of an illustrative embodiment of the LIMS platform and associated subsystems installed into a GERAN (GSM with GPRS) network.

The metadata (data about data) database 109 contains information obtained results of analysis performed by the LIMS automated processes or by the LIMS operators on data acquired from the LMS's collected network transaction messaging and/or acquired from other databases and sources. Examples of metadata include associations between mobiles including past proximity and calling patterns. Past assessments of risk/threat levels are profiled here. The metadata could use multidimensional indexing allowing for storage and retrieval of data such as coincident timing and proximity to events, mobiles or locations of interest, mobile equipment or mobile identity changes, and associations between mobile users.

The historical database 110 contains the records (which include mobile identifier, timestamp, and cellular network location (CGI, CGI with ranging)) obtained via the LMS or from the cellular network.

The BTS (Base Transceiver Station) 117 is the GSM-defined distributed radio point of connection for the GSM radio air interface 157 network. The BTS is also responsible for encryption/decryption of data sent over the air interface.

The BSC (Base Station Controller) 118 handles radio resource management, such as frequency allocation and handovers, and in some cases transcoding and multiplexing tasks. Data streams are routed through the BSC 118 via the packet control unit to the SGSN 119 while voice circuits are routed to the MSC 120.

The SGSN (Serving GPRS Support Node) 119 provides session and mobility management for GPRS-equipped mobile devices. The SGSN 119 also serves as a router for transport of packet data streams to and from GPRS-equipped mobile devices.

The MSC 120 provides session and mobility management for GSM mobile devices. The MSC 119 also supports basic voice circuit switching tasks and as interface to Intelligent Networking and other SS7 network interconnected subsystems.

The Visitor Location Register (VLR) (not shown), a dynamic database of user account information downloaded from various HLRs 121, is typically co-located on the MSC 120 computing platform.

The HLR (Home Location Register) 121 is primarily a database of user account information of a wireless carrier's customers. The user account database contains billing information, status, current/last known network address and services preferences.

The GMLC (Gateway Mobile Location Center) 122 is the gateway, bridge, and router for location services. IP-based interfaces such OMA-defined MLP or Le interface are interconnected via the GMLC 112 to the SS7 network-based nodes over such interfaces as the Lg interface (to MSC 120), Lc interface (to SCP (not shown), or Lh interface (to HLR 121) interface. Basic administration, authentication, accounting and access control functions for location services may also be implemented on the GMLC 122.

Exemplary LIMS Network

FIG. 2 details an example of the LIMS network. In this example, the LMSs 201 202 are separate from the LIMS deployment 200, although in practice, the functionality could be combined on the same server platform or cluster of servers. The LIMS and LMS are deployed in a 1-to-1 or 1-to-many configuration based on needed capacity, number of wireless carriers to monitor, or geographic service area.

The LIMS controller 203 uses generic digital data interconnects to the LMS platforms 201 202. The controller 203 is both a packet router as well as a firewall providing authentication and access control. As part of the router function the controller 203 performs event scheduling, packet filtering and inter-subsystem communications. Provisioning, monitoring and control of the LMS network 201 202 is also performed via the controller 203 communications interfaces 211 212. Said controller 203 also contains the aforementioned control logic and algorithms for generating complex triggers and may be a single or cluster of servers.

The controller 203 directs LMS obtained wireless network transaction information to database 204 via a high speed database interface 213. Additional information such as high-accuracy location, association data (metadata), and sensor fusion (such as image recognition, photos, videometric identity) data may be stored on additional databases 205 that may be remotely housed or internal to the LIMS deployment 200 (as shown). The interface 214 to the other databases 205 is dependent on deployment specifics but can take the forms of any of a number of local-area-network (LAN), wide-area-network (WAN) or database specific interfaces.

The controller 203 allows for recovery of databased wireless network transaction information from the database 204 via 213 via the generic Ethernet interfaces 222 218 which interconnect the local user stations 210 and remote user stations 207.

The LIMS deployment's Local Area Network 217 offers packet data connectivity to all subsystems under the controller's 203 rules. The controller connects to the LAN 217 via Ethernet 216 as does the internal location-based services applications server 209 via link 219 and the Map database 208 via data link 220.

The local user stations 210 and remote user stations 207 via the controller 203 and the associated packet data network 217 have access to the databased wireless information 204, but also internal location-based services applications 209, external location-based services applications 206 and digital mapping database(s) 208. The external applications 206 and remote user stations 207 interconnections 215 and 216 may take the form of a variety of transport links which are translated by the Bridge 223. The Bridge 223 also supports additional authentication, access control, monitoring, and intrusion security for the external or remote components 206 207.

Illustrative Example of Complex Triggers

LIMS-IED Scan Feature

A LIMS user can pre-check a route that someone will soon travel for potential mobile phone detonated LEDs or individuals waiting to ambush a vehicle such as using a wired IED (or use of other weapons) along specific roads and areas. The LIMS user will draw geo-fence around route to be taken. The LIMS will run a specialized algorithm that will first look back into the historical database 110 for a predetermined period of time and create a list of all mobile devices that could have had presence in the area in the timeframe based on the best location information available, available events and interpolation between events, locations and timestamps. This will include mobile devices with location update events only (such as if idle and stationary) as location updates are periodic based on network operator configured timeouts. This configuration would be known and used in consideration of how far back in time the scan must look to determine potential mobile devices in the area. Additionally, any mobile devices with recent activity appearing to linger around area of interest or which turned the mobile device on or off in conjunction with the above. Additionally, further enhancements such as use of known terrain features, commonly travel routes and possible overlook points can be included in the analysis. This will create a list of candidate mobile devices that may be in the area and can provide higher priority to devices that show a higher risk profile based on user input data.

The LIMS algorithm will then use various means to automatically obtain a high accuracy location on each device on the list. Devices active on a call or data session can be immediately located and determined if still in or near the area of interest. Devices not currently active can be stimulated by using advanced triggers such as ATI or NULL SMS, depending on network type and supported capabilities, then high accuracy location is possible on all such devices and this determines their immediate location. If they are still in the area, they will now show up on a threat list and map to the user with information on how long they have been there. The LIMS will then keep tracking these devices periodically until they leave the area of interest and any others that may enter the area until the algorithm is disabled.

It is understood the above description of the algorithm is illustrative and can be changed and enhanced to use any of the data sources mention above. It is also understood that this approach will have challenges in highly populated areas where there are potentially thousands of mobile devices in and around a define area of interest. So while this approach is most useful in less populated areas, is can be tuned and enhanced to work in more populated areas via the same means. In this case, the human user may have more a larger threat list to analyze and make a judgment call. In all cases, the resulting information is useful is assessing risk and potential threats along a route before it is traveled. These results can tell the user where there is a potential IED on a roadside (mobile device detonated IED) or where there is one or more lookouts sitting idle along a road where there may be a manual IED or other ambush planned. The users can then utilize the provided information as they deem fit, such as identifying an alternative route with less risks identified, or directing other surveillance technologies to the area to validate the information, or even testing the device as follow.

Illustrative Example

Remote IED Detonation

In the above example, if there has been potential mobile device detonated IEDs identified based on the LIMS provided information, alternative intelligence and or human intelligence, the user can decide to use the LIMS to stimulate the potential mobile device detonated IED by sending it a normal SMS or placing a call to the mobile device. If it is a typical mobile device detonated IED this will cause it to detonate in a controlled manner. If the device was not an IED, then no harm was done.

FIG. 3A illustrates using the LIMS for detecting a command-detonated IED scenario as well as detailing the general LIMS enabled features used in the analysis of historical and real-time data. The LIMS network (which includes the LMS) is deployed in a carrier network (or multiple carrier networks). The LMS component is pre-set with a set of triggers that passively capture a selection of network events 301. These triggers include mobile-origination, mobile-termination, location update, IMSI attach and IMSI detach and can include additional mid-call event triggers such as Network Measurement Report (NMR). This background passive monitoring and databasing of events continues on an indefinite basis. The LIMS can add or delete network transaction triggers in the LMS at time as needed to facilitate the complex associative triggers used in the analysis software such as the DSS in the LIMS.

When an area (such as a roadway) is to be secured, the user determines the geographic area to be secured and the time window for the operation 302. The LIMS, in response, starts a parallel series of operations. First, a historical analysis of monitored events from the historical database begins 303. Secondly, a real-time analysis of current activity in the selected area is started 304. For both the real-time and historical analysis, the best available location derived from the cellular system information (cell-id, sector, timing and or power-based ranging) in the current or historical monitored information is used to find mobile devices locations in the approximate area in and round the selected geographic area.

Once the first, rough set of mobile's identities and locations are determined, the LIMS schedules its attendant high-accuracy Positioning Determining Equipment, sets internal filtering and triggering, and then silently polls the first set of mobile devices (this active, silent polling uses the AnyTimelnterrogation (ATI) or null-SMS capability provided by the SMS-C or the GMLC (in CAMEL Phase III, IV). High accuracy location includes TDOA, AoA, TDOA with AoA and hybrids.

Using the LMS and PDE, the network transaction triggering and associated radio uplink transmissions are detected and a high accuracy location is performed 307. It is the LIMS' responsibility to schedule the PDE resources and active polling as to optimize the location rate, location accuracy (possible retries may be needed) and location over the selected area (for instance, the LIMS may schedule mobile devices closer to the start of a route first, or mobile devices with the highest possibility of being next to the route).

As high accuracy locations become available, the LIMS begins analysis of the high accuracy location historical behaviors. The LIMS removes mobile from the first list that are not in proximity to the route. Since new mobile devices may enter the selected area at any time, the real-time analysis 304 can cause additional scheduling of high accuracy resources 305, active polling 305 and high accuracy location 307 at any time in the selected time window. Using the rules based decision support system, the newly refined second list of mobile devices is analyzed for suspicious behaviors and location proximity to the route 308 (for instance, a mobile phone that has never made a call since power-up is in close proximity to the road through multiple periodic registration cycles is flagged). The DSS prioritizes suspicious mobile devices and presents the entire second list of mobile identifiers, locations, and priority to the user 310 as a threat list. The user can then select from a variety of options detailed above. The LIMS and attendant subsystems continue operation until the time window closes or the present operation is discontinued by the user. Events generated by the LMS in response to the initial set of triggers or additional sets of triggers within the LIMS as well as the high accuracy locations generated all get stored in the historical database indexed by time, mobile identifiers, event, and location metadata generated during the analysis by the LIMS is stored in the metadata database which could be indexed by time, mobile identifiers, event, and location, relationship and priority for future use or review. Using the delivered risk assessment, the user can choose to disable the mobile device 311 via several methods. Working with the local wireless operator, the mobile device can be denied further network access. The device may be messaged (short message service (SMS), or called since the identity including the dialable directory number is known (perhaps resulting in detonation). Alternately, local personnel can be vectored to the position for manual observation and disablement. If not disabled, the device may be monitored for addition radio activity by the LIMS, or placed under observation by local personnel, aerial assets, or video means.

Illustrative Example

Remote IED Detonation

In many scenarios, it is desired to gain information on associates of an individual and their corresponding mobile device. One such was to automatically obtain this is via LIMS where it can set relational based triggers. One example of a relational based trigger is any device that makes contact with a specific device, denoted by a unique ID (such as IMEI, IMSI, and MSISDN). When the other device sends (or receives) an SMS, data message or phone call to (or from) the specific device, the LIMS can trigger high accuracy locations on the other device instantaneously. This could be used to allow a potential IED to be detonated by sending a “decoy” to the area while having set the LIMS to do a relational trigger on this device. When the IED goes off, the LIMS will immediately locate the calling/sending device and provide the information to the LIMS users. Even if the calling subject turns off the device immediately thereafter, having high accuracy location information on the calling subject immediately is very useful information as nearby resources can be deployed or other mobile devices in the proximity can be flagged as potentially belonging to the same subject or associates thereof and then tracked. If the actual trigger device is not turned off, it can then be tracked via high accuracy for a user define period of time. In both cases, the tracking of such devices could enable collection of additional information and the apprehension of the suspect.

In general, this could automatically be extended using relational based triggers to then automatically obtain high accuracy locations and information on any other mobile devices that communicates with this device such as through SMS or calling. This can be iterative and then produce a set of relational data that is stamped with high accuracy locations of each device in the list at the time of transaction and optionally thereafter. Another example of relational based triggers is when two or more mobile devices remain in the proximity of one another (even if the said devices never communicate directly between one another), and once validate using high accuracy, appear to be associated based on various correlative techniques such as being together when moving fast along a road (in a car together) and tend to remain together for periods of time while moving around.

The LIMS could determine potential candidates for this type of match based on algorithms based on lower accuracy information and then trigger high accuracy location as needed to validate or invalidate potential matches. This could be based on a known mobile device, (such as a known mobile and look for other mobile devices that correlate geographically in time) or could be a completely random brute force approach (LIMS looks into historical database and randomly finds and determines matches) or geographically based (devices that frequent certain areas to be used as a starting point and then seek to find others that correlate). Once the LIMS has determined geographical association with two or more mobile devices with a high probability, the LIMS user can then be alerted and the metadata created stored for later use.

Illustrative Example—Behavior Based Triggers

Another aspect of the LIMS capability is in the detection of behaviors of interest and identifying specific mobiles or mobile users associated with such behaviors of interest. These behavioral complex triggers use the LIMS capabilities, such as, e.g., the previously cited U.S. Pat. No. 7,783,299, “Advanced Triggers for Location-based Service Applications in a Wireless Location System,” that allow for radio or network events (corresponding to specific messages or groups of over-the-air, inter-network or intra-network messaging) to generate high and/or low accuracy location estimates. A triggering event, one that initiates location estimation, may be a detection of a particular message or a field within a specific message. Examples of detectable network or radio events (also called network transactions) in a wireless communications network include: (1) Mobile originations/terminations; (2) SMS originations/terminations; (3) Mobile Attach/Detach (packet data) events; (4) Registration/Location/Routing Update (that is, a “location” update for the purposes of mobility and roaming as opposed to a network-based (U-TDOA, AoA, ECID) or mobile-based (A-GNSS, GNSS, OTDOA, ECID) location event; (5) Handovers; and (6) Call Releases.

Over time, a database of historical information is developed (collection phase) of mobile identifiers and triggered events. The data collection phase may target any mobile device, any set of mobile devices, or a specific area in the wireless communications network (WCN) service area. Selection of a mobile device may be by any of the detectable mobile or network identifiers associated with the mobile device.

Data from the collection phase is then analyzed for suspect behaviors and an index probability is assigned to each mobile. The Analysis phase may include information imported from off-line, non-wireless sources. The Analysis phase may be performed automatically periodically, ad hoc in response to a set triggering event, or manually at any time.

Illustrative Examples of Advanced LIMS Scenarios

These illustrative examples are used to highlight the capabilities of the LIMS. Both network-based (U-TDOA, AoA, ECID) and/or mobile-based (A-GNSS, GNSS, OTDOA, ECID) wireless location techniques may be used to accomplish geo-location of mobile devices. Selection of the wireless location technique may be based on the mobile device's capabilities, the serving wireless communication network's capabilities or the operator's discretion.

Area Presence Determination

In this illustrative example, the site (area of interest (AOI) could be at a construction site or other area where users wish to insure there are likely no mobile devices in the area prior to an event, such as demolition of a building.

FIRST STAGE—(Historical scan) The LIMS can use a historical view of any and all mobile devices that could have been in the area in the last X hours (where X is a variable) based on low accuracy historical data. It can then use the most recent event that was possibly in the area of interest, and check to see if there is a more recent event showing the particular mobile device was somewhere else outside of the area of interest, showing it likely moved away. This would eliminate this mobile device from consideration.

SECOND STAGE—(final determination if in Area of Interest AOI)—Other mobiles that show recent events that could be in the area of interest and do not show more recent events farther away, can then be considered as possibly in the AOI. The LIMS can then automatically ping these mobile devices in real time using high accuracy and determine if they currently are or are not in the AOI. If any mobile devices are, they continue to be tracked using high accuracy.

THIRD STAGE—(continue to scan for a period of time Y (where Y is a variable))—The LIMS can then continue to monitor the AOI and track mobile devices known to be in the area using high accuracy. In addition, any new events that occur where the mobile device could be in the AOI are located using high accuracy and are either eliminated from consideration or added to the list of mobile devices in the AOI.

FOURTH STAGE—(steady state determination)—After a period of time Y, the LIMS can be reasonably sure what mobiles are in the AOI as long as the scan time “Y” is longer than the typical periodic location update time of the networks. NOTE: this does not guarantee there are no other mobile devices in the AOI as they could have entered the AOI in an idle state since the last periodic location update time, but it does provide a way to scan for a majority of likely mobiles in the target area in an automatic fashion.

Association by Proximity

(A) Synchronous Geo-Profile Correlation—One Person, Multiple Mobile Devices

LIMS can use location information to associate two or more mobile devices as being associated even if these mobiles devices never call or text each other. Historical information can be mined to find mobiles with highly correlated geo-profiles as a function of time. Such mobiles would exhibit essentially the same location profile over a time range but may not have any specific events linking them together except for approximate location.

Collection and Analysis can be done over a longer time range to increase correlation and show that these 2 (or more) mobile devices may be being carried by the same person, and hence knowing the identity of one now provides the identity of the other and can be linked in link analysis. Also high accuracy surveillance can be enabled on these two mobiles for a period of time to further validate this association for a period of time.

(B) Synchronous Geo-Profile Correlation—Associates

The LIMS system can further determine that 2 (or more) mobiles may be highly location correlated for periods of time but then are clearly not at other periods of time. This indicates the two persons are associates and spend time together (meetings at static locations or moving around together) but at other times (such as night) go to different locations.

High accuracy surveillance can then be used by the LIMS to validate this association as well as the periods where they are apart. These two mobiles may never call each other thus such association would not be available through traditional call analysis. This could be for validating employees are working together during the day as they are supposed to, such as a delivery team, or police officers sharing a patrol car.

(C) Asynchronous Geo-Profile Correlation—Indirect Associates

Here, a specific mobile device may exhibit a geo-profile and there may be one or more mobile devices that have a very similar profile but at different times. This could be used to determine that 2 or more mobiles frequent the same sites but at different times, perhaps on different shifts. This shows an indirect association between the specific mobiles, such as dump truck drivers bringing loads of dirt from a construction site to a fill area, and that others exhibit the same location behavior but out of synch with each other with respect to time. Or the dump truck driver may work an 8 hour shift and another driver is traversing the same route during the next 8 hours. In this case, the association is they have the same job. Here again, the associated high accuracy wireless location system can be used to validate this assumption.

(D) Phone ID Determination

Many prepaid phones have no user identity associated with them, except for the dialable numbers. As discussed in TruePosition's U.S. patent application, Multi-Sensor Location and Identification, Ser. No. 12/633,672, even if local or national authorities require user registration for prepaid phones, there will always be fraud or black markets for such devices. The user of a specific mobile may be able to be determined by their geo-profile. Information such as where they tend to spend the night and where they are during the day can be added to the call information available to help identify the owner/user of a specific mobile.

Avoidance Tactics Detection

The LIMS can be used to detect avoidance strategies used by those attempting to avoid being detected.

Prison Phone Use

One such example is a prisoner who has a smuggled a phone into a jail facility. The prisoner will only turn the phone on for a brief time, make a call or two (or send/receive text messages) and then shut it off. The LIMS can mine the historical database for such behavior patterns and then create a list of candidate phones that exhibit such behaviors. High accuracy surveillance can then be used when such phones are used again to determine the exact location of where this activity is taking place. This will indicate if this mobile is in a prison or area where phone use is restricted. LIMS can also send real-time automated alerts to authorities so they can take quick action.

General Avoidance—Signaling

If the phone exhibits the above behavior but in different locations, then it is not a prisoner but may be an indication of illicit behavior. LIMS can then mine the historical information and look for other mobiles that are in the same areas at the same time on a statistical basis to determine possible other associates (above) or if this person is carrying two phones. The two phones can then be looked at for additional correlations, such as one is always on and when it receives a call or message from a number, the user turns on the other phone and makes a call or sends a message to a specific number. The first phone is used as a signal and the second phone is used for the communication.

General Avoidance—Limited Duration Disposable Mobile Devices

A person uses a different prepaid phone every week. Also each week, his/her associates change phones so they are never the same phone numbers used for more than a week. LIMS can detect this behavior by analyzing collected information from the LIMS database for such behaviors and associate it to the numbers called to/from.

A geo-profile of such mobiles can then be built and used to predict when and where the switchover to new devices will occur. Then the new devices can be determined quickly and the user or group of users can be tracked despite their efforts to avoid detection.

High accuracy location can then be used to provide additional detail on the behavior of such individuals and their associates and provide for a faster and more accurate correlation to new devices when switched.

Kidnapping Scenario

In this scenario, the kidnapper carries two mobile devices (in this example mobile phones), a primary phone “A” that he uses to communicate with his accomplice or boss, and secondary phone “B” which is a throw-away phone. In some cases, the “B” phone may be the victim's own cell phone or a stolen phone.

The kidnapper uses phone “B” once and throws it away. The goal of this procedure is to identify phone “A” and network identifiers or limit the number of possibilities for phone “A”. Given that the LIMS tool may be configured to collect and archive all network events in the service area to the database, the LIMS system can execute the following procedure: 1. A kidnapper calls using phone B for ransom at time T1. We can immediately identify the phone B identifier and locate the phone at time T1, The resulting low-accuracy (cell-based) location is denoted Location L1. (Note: Kidnapper tosses phone B—he has no more use for it.) This first step can be either in real-time location with knowledge of the past kidnapping event or in post-event analysis using LIMS given the dialed number and the known time T1. 2. The LIMS operator sets up a data mining campaign C1. This campaign will be centered around location L1 at time T1 plus or minus the location update set by the network (let us assume it is half an hour). This campaign will capture all phones that are possibility in close proximity with phone B at time T1. (Note that phone A will be one of these phones.) 3. The next day or hours later, the kidnapper uses another throw-away phone “C” to communicate with the kidnappee family at time T2 for ransom. 4. We can immediately identify phone “C” identifier and locate the phone at time T2, and the resulting location is denoted Location L2. (Note Kidnapper tosses phone “C”—he has no more use for it.) 5. The LIMS operator sets up a second data mining campaign C2, This campaign will be centered around location L2 at time T2 plus or minus half an hour. This campaign will capture all phones that are in close proximity with phone C at time T2. (Note that phone A will also be one of these phones.) 6. Now we look at the intersection of mobile and network identifiers of C1 and C2. LIMS provides an automated tool to perform this identifier intersection operation. 7. The LIMS result should identify a small set of identifiers that are located at L1 at Time T1 and L2 at time T2. Note that phone A is part of this set. 8. At this time all matches are possible targets, or if there is a third or subsequent call, the LIMS operator can repeat the identifier intersection operation and results from a Campaign C3 (or additional) to identify a single target.

Secondary Triggers for General Surveillance:

Once the LIMS device is deployed into a service area, specific triggering events may be established to alert operators of suspicious behavior or threats. Location surveillance of specific mobiles can be triggered by additional conditions, such as:

1) When they enter or leave a specific area such as a job site. Using the LIMS, a geo-fenced Area-of-Interest is established and a set of mobile identifiers associated with that AOI is provided. Mobile devices that execute a network transaction within the AOI are detected as are the pre-set mobile identifiers. Using the network events associated with the AOI and the network events associated pre-set mobile identifiers, entry and exit from the AOI may be determined and surveillance may be activated or de-activated.

2) When they make/receive a call/text to/from another mobile device that is under surveillance. Using the LIMS, a primary trigger is established based on a suspect mobile device's identifier(s) and dialable number. Any mobile phone that contacts (via messaging, data connection or voice call) to the suspect mobile is then added as a trigger for surveillance.

3) As a function of day and time (e.g., only perform surveillance on mobile when they are supposed to be working). Using the LIMS, a geo-fenced Area-of-Interest is established and a set of mobile identifiers is associated with that AOI. Mobile devices that execute a network transaction within the AOI are detected as are the pre-set mobile identifiers. Using the network events associated with the AOI and the network events associated with pre-set mobile identifiers, entry and exit from the AOI may be determined and surveillance may be activated or de-activated based on that condition and the local time-of-day.

4) If they turn their phones on, make calls (or texts) and turn off. This secondary trigger is based on a repeated sequence for a mobile device, specifically, the mobile device preforms a power up registration, sends messaging, establishes and completes a data session or makes a voice call, but few (or no) periodic or other registrations are associated with the mobile device and a power-down de-registration is detected. The LIMS may be set to detect and automatically locate such mobile devices based on this secondary trigger.

5) If they turn their phones on, make calls (or texts) and turn off by removing the battery. This secondary trigger is based on a repeated sequence for a mobile device, specifically, the mobile device preforms a power up registration, sends messaging, establishes and completes a data session or makes a voice call, but no periodic or other registrations are associated with the mobile device and no power-down de-registration is detected. The LIMS may be set to detect and automatically locate such mobile devices based on this secondary trigger.

6) They, the caller, use failed originations to signal the callee. The callee then originates a second call to the original caller or a third party. The LIMS system detects the incomplete first origination and sets a trigger so that any secondary follow-up call placed back to the first originating phone or to a third party can be detected, identified, located, and logged. In contrast, use of billing records or call detail records (CDRs) cannot identify this scenario since incomplete call information is normally not retained by the wireless communications network operator.

7) They forward calls via a relay device. As an example, a suspect carries wireless device “A” but he does not disclose the phone number to anyone, instead he sets up a second communications device “B” (Entity “B” could a be wireless device, could be landline station or a Voice-over-IP facility) to call forward all incoming calls from device “B” to Mobile device “A”. Note that device “B” could be set up remotely, could be a virtual device running as an application on a mobile or fixed computing device or it could be a real mobile device with the requisite forwarding mechanism setup thru the wireless or wired network operator facilities.

When an agent or agency knows device “B” but would like to discover Mobile device “A” and the location of the suspect possessing the “A” mobile device, the LIMS system may be used to discover mobile device “A” identifiers (e.g. the phone number, serial number, etc.) and its location. In this example scenario, a mobile device “C” sets up a call, sends a message or creates a data session with to device “B”. Mobile device “C” may be an unknown 3rd party mobile device or one used by the agent or agency controlling the LIMS system.

In this scenario:

Step 1—Discover Mobile device C in real time: The agents sets up a query in real time to discover all mobile devices that perform Mobile origination Voice or Text with dialed digits showing device B. The results set will contain Mobile device C as the latest record.

Step 2—Discover Mobile device A. Now that we know Mobile device C, the agent sets up a query in real time to discover all mobile devices that receive a mobile device call or Text from Mobile device C. The results set will contain Mobile device A as the latest record and its appropriate location.

Since the agent/agency does not know if device “B” has been forwarded or not, one way to establish that ‘this is the case’ is to perform a location request in deployed and using un-deployed areas to eliminate these possibilities.

All of the above procedures could be performed in an automated format or manually. A similar procedure could be established for call spoofing (meaning, dial a number from Mobile device “A” to Mobile device “C”, mobile device “C” receives a call from mobile device “B”. The agent only knows mobile device C and would like to locate all mobile devices that calls or messages mobile device “C”.

In this scenario, the target has call spoofing set up, the agent sets up a query in real time to discover all phone numbers that performed incoming calls or text to mobile device C. Phone number B would be the most recent number. Knowing phone number B, the agent can set up a query to identify all devices that perform mobile origination (text or voice) to phone number B. The result set will contain mobile device A (the target) which is the latest record and its appropriate location.

FIG. 3B, LIMS Campaign

FIG. 3B shows the high level procedural flow for a LIMS campaign. As described in U.S. Pat. No. 8,224,348 issued Jul. 17, 2012, included herein via reference, a Location Intelligence Management System (LIMS) is a data capture, storage and decision support system that utilizes available data (both past and real time) from multiple sources (such as wireless networks, wireless location network, and off line sources such as network information, geographic information, manually entered information and geo-spatial data) to optimize utilization (scheduling and selection) of wireless location resources across multiple users and entities to produce location-aware intelligence. The LIMS contains the algorithms, control logic, data storage, processors and input/output devices to analyze past and real time data obtained from multiple sources in combination or separately, to produce intelligence in the form of metadata not otherwise reasonably or easily obtained. These algorithms can iteratively use previously generated metadata to automatically contribute to new analysis, which will use both real data (past and real time) as well as metadata. Such analysis would produce information such as: identifying potential behaviors of interest, identifying specific mobile users associated with such behaviors of interest, associations between mobile device users and mobile device user identification when no public ID is available (such as with prepaid mobile devices). The LIMS can then manage Position Determining Equipment (PDE) location resource utilization based on a combination of factors including but not limited to location priority, location accuracy, wireless location system(s) capacity, the geographic distribution of PDEs, terrain, man-made information (known tunnels, buildings, bridges, etc.), network information (cell distribution, coverage, network topology, network status, etc.), for performing locations on traffic channels, control channels and data sessions.

As described in U.S. patent application Ser. No. 13/490,745, filed: Jun. 7, 2012, included herein via reference, the LIMS may be further configured with computer software to utilize data from multiple sources to produce location-aware intelligence including the creation of geo-profiles for mobile devices. The geo-profiles include location, event, and time information for the mobile devices.

Such geo-profiles can be analyzed to detect aberrant or potentially aberrant behaviors, or what we refer to as “behaviors of interest,” or “behavior-based triggers”. For example, as described below, an aspect of this embodiment is the LIMS' capability to detect behaviors of interest and identify specific mobiles or mobile users associated with such behaviors of interest. These behavioral complex triggers use the LIMS capabilities that allow radio or network events corresponding to specific messages or groups of messages to generate high and/or low accuracy location estimates. A triggering event that initiates location estimation may be a detection of a particular message or a field within a specific message. Over time, a database of historical information including mobile identifiers and triggered events is developed (collection phase). The data collection phase may target any mobile device, any set of mobile devices, or a specific area in the wireless communications network (WCN) service area. Selection of a mobile device may be by any of the detectable mobile or network identifiers associated with the mobile device. Data from the collection phase is then analyzed for suspect behaviors and an index probability is assigned to each mobile. The analysis phase may include information imported from off-line sources and may be performed periodically, ad hoc in response to a set triggering event, or manually at any time. Illustrative examples of advanced LIMS scenarios include area presence determination, association by proximity, detection of avoidance tactics, and general surveillance using secondary triggers.

The first stage of an active LIMS campaign 324 is Setup 320. The Setup 320 includes deployment of a LIMS system to cover the area of interest within the service area of a wireless communications network (WCN). The LIMS deployment options include standalone deployment, co-deployment with a Wireless Location System (WLS) and/or monitoring probes within the carrier infrastructure, and interconnection to the carrier network's administration or command and control framework. Although nominally deployed with a first WCN, a LIMS and associated wireless probes may be used to monitor radio events in geographically overlapping or neighboring WCN.

In data collection 321, the WLS, a network of wireless receivers and/or wired probes, provides the LIMS system with call-related data to build a database of events over time. Non-call related information (e.g. radio network information, geographic information, geo-spatial data, and manually entered information such as points of interest or timed/dated events) is also provided to the LIMS.

Data Collection 321 may also include the entry of additional historical call data loaded into LIMS from the wireless carrier'(s) Home Location Register (HLR), Home Subscriber Server (HSS), Billing records, call detail Records database(s) or other call/caller related information such as that retained for production in law enforcement requests for call data. Loading of such historical data could be used to extend the LIMS database in time or in coverage, or to configure the LIMS for use in a standalone deployment.

Once call information is being gathered or loaded, the LIMS can begin analyzing the call data. In the data evaluation 322, a set of rules for analysis of the data is entered. The combination of call data, filters such as geo-fences and time-of-day are used to build complex triggers that, when then used with off-line data 326, is then used to create metadata for each call or caller. The newly created metadata allows the LIMS to perform analysis where the location of a mobile is used as a proxy to identity, purpose and relationships between mobile users. The same metadata can be used to enhance forward looking algorithms which in turn produce new complex triggers which then can be used for further analysis.

When, during evaluation 322, the rules for analysis flag a call, caller, or group of calls, a response 323 is called for. This response 323 may be customized and prioritized, e.g. the response could be an alarm to the operator terminal, generation of an ad hoc report, generation of entry in a periodic report, or an immediate real-time automated response dependent on the level of integration between the LIMS and non-LIMS systems.

Once the active campaign 324 has ended, the results of the evaluation 322 (the rule set, metadata, generated triggers) and any data generated in the response 323 may be stored as offline data in a database 326 for logging or reuse in later campaigns.

FIG. 4A, Location of Tunnel Portal

FIG. 4A illustrates a rural scenario for location of a tunnel portal. An international border 401 exists between relatively uninhabited areas of separate countries. A road 402 roughly parallels the border. No official border crossings exist in the local area. The border 401 is walled or fenced or under continuous surveillance by cameras or other sensors. The local Wireless Communications Network (WCN) provides radio coverage 409 over the second, near side tunnel mouth 405.

A first, far side tunnel mouth 403 has been dug and a border-crossing tunnel 404 constructed with the second portal 405 on the other side of the border 401. The tunnel mouths 403 404 have been concealed by camouflage, vegetation, or dug out so terrain features preclude easy observation from the road 402.

Under observation of the LIMS system, collection and analysis of radio network transaction information from the area is performed. For instance, registrations, SMS, call originations/terminations, data transfers, attachment events, and control messaging may all be observed. In this example, registrations from mobile devices emerging from the tunnel 404 are noted and located to high precision. The LIMS PDE receivers can be placed so as to maximize the precision over a local area. The LIMS PDE receivers can also be tuned to receive registrations from over the border 401 and determine and locate a second cluster of registrations on the foreign WCN if the tunnel mouth 403 is being used as an exit.

The resulting cluster of registrations 407 408 can then be used to locate the tunnel mouths 403 405. By using a threshold for registrations as well as time-of-day, weather conditions, seasonality, or geology, false positives can be reduced. Over time, even solitary power-up registrations 406, not associable to a cluster 405 can accumulate and lead to tunnel mouth discovery.

FIG. 4B, Alternate Scenario for Location of Tunnel Portal

FIG. 4B illustrates an alternate rural scenario for location of a tunnel portal. An international border 401 exists between relatively uninhabited areas of separate countries. A road 402 roughly parallels the border 401. No official border crossings exist in the local area. The border 401 is walled or fenced or under continuous surveillance by cameras or other sensors. A first tunnel mouth 403 has been dug on the far side of the border and a border-crossing tunnel 404 constructed with the second mouth 405 on the near side of the border 401. The tunnel mouths 403 405 have been concealed by camouflage, vegetation, or dug out so terrain features preclude easy observation from the road 402.

The local Wireless Communications Network (WCN) does not provide radio coverage 409 over the second tunnel mouth 405 but does cover the nearby roadway 402 with radio coverage 409. Once idle mobile devices come into the coverage area 409, they quickly attempt to register with the local WCN. The non-local WCN (not shown) on the far side of the border does not provide coverage to the area over the border.

Under observation of the LIMS system, collection and analysis of radio network transaction information from the area is performed. For instance, registrations, SMS, call originations/terminations, data transfers, attachment events, and control messaging may all be observed. In this example, registrations from mobile devices entering the coverage area 409 are noted and located to high precision. The resulting cluster of registrations 407 can then be used to assist in the location of the second tunnel mouth 405. By using a threshold for registrations as well as time-of-day, weather conditions, seasonality, or geology; false positives can be reduced. Over time, even solitary power-up registrations 406 from mobiles devices turned off before leaving the tunnel 404, not associable in real-time to a cluster 405 can accumulate and lead to localization of a trail that leads to a tunnel mouth 405.

FIG. 5, Location of Tunnel Mouth in Urban Area

FIG. 5 is a sequential illustration of the location of tunnel mouth using LIMS in an urbanized area. In this illustrative scenario, a border crossing tunnel 501 has been dug between a first 506 and second 508 buildings going underneath the border 502 and border defenses 503. The buildings provide concealment of the first tunnel mouth 514, the second tunnel mouth 513 as well as any digging equipment, extracted soil, people and/or smuggled (or to-be-smuggled) goods.

The border control in this example scenario is already enforced by a border wall 503. A monitored border crossing 504 is served by a road and highway network 517 interconnecting both sides of the border. Distinct Wireless Communications Networks (WCNs) serve each side of the border with no or minimal cross-border coverage.

This urban scenario is complicated by the presence of buildings 505 506 on the first, far side of the border 502 and multiple buildings 507 508 516 on the second, near side of the border 502.

Deploying and configuring a LIMS system with associated high-accuracy WLS to cover the area, a campaign collecting all call and caller data is performed. A geo-fence is constructed to detect entry into the area on the second, near side of the border. The geo-fence uses the available geo-spatial information determined from the wireless network configuration and use (cell, cell/sector, cell/sector and power, cell/sector and timing, cell/sector timing and power). For the area under observation of the LIMS system, collection and analysis of radio network transaction information from the area is performed. For instance, registrations, SMS, call originations/terminations, data transfers, attachment events, and control messaging may all be observed.

To detect the second, near side tunnel mouth 513, the LIMS initially uses location registrations (also known as paging area updates, routing area updates, tracking areas updates). Collecting and locating registrations, the LIMS removes those 512 geographically associated with the legitimate border crossing 504. A second cluster of registrations 515 is found. An initial evaluation finds the prevalence of registrations, initial attachment messaging and lack of previous entry into the LIMS database raising the risk metric for these phones and the building 516 geographically associated with the cluster 515. However; upon evaluation with off-line data, the cluster 515 was found to be associated geographically with a wireless carrier store and therefore removed from consideration. Non-clustered registrations 510 are noted and kept for further, future evaluation.

In one specific cell 509 of the geo-fenced area, a cluster of registrations 511 was located. Upon evaluation, it was found that many of the mobile devices were new to the LIMS database and registration included attachment messaging. Based on the evaluation, the building 508 geographically associated with the suspicious cluster 511 was reported for observation and potential searches for the tunnel mouth 511 and any smuggled goods or people.

FIG. 6, Over the Border Airdrop Detection

FIG. 6 geographically illustrates over the border airdrop detection using LIMS. Under observation of the LIMS system, collection and analysis of radio network transaction information from the area is performed. For instance, registrations, SMS, call originations/terminations, data transfers, attachment events, and control messaging may all be observed.

In FIG. 6, an over-the-border incursion by a light aircraft (e.g. an ultralight aircraft) is depicted. In this illustrative scenario, the border 601 is wall, fenced, patrolled or otherwise under observation. Smugglers use light aircraft and commercial wireless communications (e.g. cell phones) to smuggle goods over the border 601. The aircraft 604 follows a flight path 605 that stays comparatively low to the ground, under-the-radar, to prevent detection.

Upon entering 606 the coverage area 603 of the local base station 602, the mobile device carried by the pilot registers with the local WCN. The registration 606 is noted and located by the LIMS's PDE component. The location data (which includes speed, bearing and potentially altitude) allows LIMS to classify the mobile device as an aerial incursion (for instance, map data shows proximity to the border 601 and no road surface associated with the location, speed and bearing).

The LIMS then uses the real-time connection to the WCN network (for instance via a Mobile Positioning Center (MPC), Gateway Mobile Location Center (GMLC) or similar facility) and the highest accuracy wireless location system available to ping the Mobile-device-Of-Interest (MOI) (e.g. using AnytimeInterrogation (ATI), null SMS, or wireless network-technology specific silent messaging mechanism). Repeated pings of the MOI allow repeated high accuracy locations 607 and plotting of the flight. The furthest incursion area 609 is noted based on the flight plot and in this scenario, the proximity to a road. The LIMS notes the furthest incursion area 609 and continues to ping the MOI until communications is lost.

Using call data for the serving cell 602, the LIMS searches its database for a call between the MOI and any other mobile device. In this scenario, a second MOI 608 is discovered in the area and as being the sender of a call (or messaging) to the first, aerial MOI. Based on that call and the proximity to the predicted drop zone 609, the second MOI 608 is flagged for further tracking and reporting. Using the over-the-border and cross-network capabilities of the LIMS and WLS, a registration event 610 of the aerial MOI may be detected and located over the border.
